ACETYLENE-GAS GENERATOR.`

SPECIFICATION forming part of Letters Patent No. 791,540, dated June 6, 1905.

- Application iiled July 30, 1904. Serial No. 218,842.

To a/ZZ whom, t may concern:

Be it known that I, SYLvEsTER C. CORBIN, a citizen of the United States, residing at Tipton, in the county of Cedar and State of Iowa, have invented a new and, useful Carbid-Feed for Acetylene-Gas Generators, of which the following is a speciiication.

This invention relates to acetylene-gas generators, andk has for its principal object to rovide a novel form of mechanism for fee ing the carbid from the carbid-container to the generating-tank.

A further object of the invention. is to provide novel mechanism for accomplishing the feeding automatically each time the supply of @as is nearly exhausted.

still further object of the invention is to provide an improved form of agitatorl or slush-bar that serves also to actuate the carbid-feeder. Y

With these and other objects in view, as will more fully hereinafter appear, the invention consists of the novel construction and arrangement of parts hereinafter fully described, illustrated. in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a Vlongitudinal sectional elevation of an acetylene-gas generator constructed in accordance with the invention. Fig. 2 is a sectional plan view of thesame on the line 2 2 of Fig. 1. Fi 3 is an enlarged sectional view of the carbid-feed valve. Fig. 4- is a transverse sectional elevation of the feedvalve on the line 4 4 of Fig. 3.

Similar numerals of reference are employed to indicate corresponding parts throughout the several iigures of the drawings.

The working parts of the apparatus are contained within-a tank 1. This will generally be of cylindrical form and is divided by an approximately horizontal partition 2 into a generating-tank 3 and a gas-containing chamber 4. From the central portion of the partition 2 extends a vertically-disposed cylindrical casing 5, the bottom of which is conical in form and is provided with a centrally disposed discharge openingv 6. The casing 5 forms a carbid-container, and it is closed bya Cap or cover 7 of suitable construction,l provision being made for firmly locking the cover in place in order to prevent the escape of gas. The two casings 1 and 5 form at the top of the main tank an annular gas-chamber in which is contained a corresponding shaped bell 8, the lower edge of which is water-sealed, and the gas is con# the lower edge of which is sealed in the water within the gas-containing chamber. The second tube is secured to the top of the gasbell and rises and falls with said gas-bell; but

l its lower end will at all times be sealed in water to prevent the escape of gas. Extending through the tube 10 is a vertically-disposed bar 15, having at its upper end an actuating'- handle 16 and its lower endbeing turned to form an agitator-bar 17, which may be turned with the bar 15 as a center in order to agitate the slush within the tank, and in order to prevent injury to the bottom of the tank, as well as to lessen the labor of moving the agitator, the tank is provided with a' small block 19, having a seating-recess into which the lower end of the vertical bar 15 may be fitted. At that side of the tank opposite the slush-bar is arrangedaloop 20 in the formof a U-shaped bar, one end of which is rigidly secured to the bottom of the partition 2, while the opposite end is free and is spaced a slight distance below the partition to ermit the entrance of a horizontally-disposed cross-bar 21, carried by the vertical bar 15, the loop thus forming a guide for maintaining the bar 21 in position.

To the bottom of the carbid-container is secured a pendent arm 24, having bearings for the rece tion of a small transverse shaft 25, to whic is secured a carbid-feed valve 26. This valve is formed of a pair of end disks 27, a curved valve-strip 28, and a partition 29, all rigidly secured together. The curved valve-strip 28 follows the contour of the bottom of the carbid-container, and its forward edge is arranged on a curved line corresponding in part to the curvature of the dischargeopening 6. To the valve is further secured an arm 30, the lower portion of which is counterweighted and rests by gravity against one side of the frame 24, thereby maintaining the valve in the closed position-that is to say, that the partition 29 extends in an approximately horizontal plane beneath the opening 6, the width of the partition bein such that none of the carbid passing throng the opening 6 can fall into the water while the partition remains in the horizontal position.

Secured to the shaft 25 is -a crank-arm 31, to which is connected a vertical bar 32, and the lower end of the bar 32 is hooked and so arranged as to be engagedby the cross-bar 21.

In the operation of the device the free end of the bar 21 is entered in the guiding-loop 20, and the hook of the bar 32 is arranged directly in the path of movement of said crossbar. The valve is in the closed position* that is to say, with the partition in a horizontal plane. As the supply in the holder is gradually consumed the bell will descend, and with it the tube 11 and the vertical bar 15, this movement continuing until the cross-bar engages the hook and turns the valve, with its shaft 25 as a center. This moves the horizontal partition to an angle of about fortyiive degrees, and the carbid contained in said partition is immediately dumped into the generating-tank. At the same time the curved valve-strip 28 moves under and closes the opening 6 in the bottom of the carbid-container, so that no carbid can ilow from the container until the valve is again restored to its initial position. As soon as the manufacture of gas commences from the deposit of carbid the bell begins to ascend, and in so doing the cross-bar 21 will be raised from engagement with the hooked bar 32 and the valve will be restored to its initial position by the counterweight-arm 30 in readiness to receive another supply of carbid.

When it is desired to operate the slush-bar, the latter is raised until the arm 21 is above the free end of the guiding-opening 20, and the arm 15 is turned and is lowered until it is seated in the recess in the block 19, after which the bar may be turned in order to agitate the slush. When this has been done, the bar is readj usted to its initial position to again act as an automatic valve-operating member.

Having thus described the invention, what is claimed is- 1. In an acetylene-gas generator, the combination with a generating-tank, of a carbidreceptacle having a bottom discharge-opening, a revolubly-mounted valve having a partition for receiving a charge of carbid and provided with a curved strip for closing the discharge-opening when the valve is tilted, an arm projecting from the valve, a gas-bell, and a manually-operable slush-bar carried by the bell and operatively connected to said arm.

2. The combination in an acetylene-gas generator, of a generating-tank, a gasometer including a movable bell, a slush-bar having an operating-stein extending through the tank, a bell movable with the latter, an arm projecting from the steln, a valve for feeding charges of carbid to the tank, and a pendent operating-arm having a hook member with which the projecting arm of the slush-bar stem engages.

8. The combination in an acetylene-gas generator, of a generating-tank, a gasometer including a movable bell, a slush-bar carried by and movable with the gasometer, an automatic carbid-feeding valve, and means carried by the slush-bar for operating the valve, said means being adjustable to position for agitating the slush without operating the valve.

4. The combination in an acetylene-gas generator, of a generating-tank, a gasometer including a movable bell, a slush-bar connected to the bell, an arm projecting from the slush-bar stem, a carbid-valve, a valve-operating arm with which the projecting arin engages, and means for guiding said projecting arm.

5. The combination in an acetylene-gas generator, of a generating-tank, a gasonwter including a movable bell, a carbid-feeding valve having a pendent. arm provided with a terminal hook, a U-shape guide carried by the tank and open at one side, a slush-bar, a stem carrying the slush-bar and supported by the bell, and an arm projecting from the stem and movable into and out of engagement with the guide, said arm being adapted to engage the hooked member of the carbidvalve and thereby move the valve to open position.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
